features/bitrot: Introduce scrubber monitor thread
The patch does following changes. 1. Introduce scrubber monitor thread. 2. Move scrub status related APIs to separate file and make part of libbitrot library. Problem: Earlier, each child of the scrubber was maintaining the state machine and hence there was no way to track the start and end time of scrubbing as each brick has it's own start and end time. Also each brick was maintaining it's own timer wheel instance. It was also not possible to get scrubbed files count per session as we could not get last child which finishes scrubbing to reset it to zero. Solution: Introduce scrubber monitor thread. It does following. 1. Maintains the scrubber state machine. Earlier each child had it's own state machine. Now, only monitor maintains on behalf of all it's children. 2. Maintains the timer wheel instance. Earlier each child had it's own timer wheel instance. Now, only monitor maintains on behalf of all it's children. As a result, we can track the scrub statistics easily and correctly.
